Bison brand toolpost concern

"Inserts"? You mean tool holders?

I use at least some Bison products -- but they come from Poland, not Oz. Those which I use (chucks and backplates) I have found to be excellent.

I did not know that they made quick-change toolholders. But it would not surprise me.

I use a mix of Phase-II and Aloris (in the BXA/Seris-200 size), and I *seriously* crank down on the setscrews -- all four of them, if the tool shank is long enough -- and I have never had a failure as a result. They (both Aloris and Phase-II) appear to be case hardened, not through hardened, as is appropriate for the function.

Good Luck, DoN.

Yes, I meant tool holders. I guess inserts sounds more like replaceable carbide tips.

Thanks for that. I hope these Bison ones are just case hardened too. I'll soon find out !

This is an interesting toolpost that at one time was also an accessory available for the Emco range of ten inch lathes, such as the V10-p - that like the Myford - don't have a whole lot of space between the deck of the compound rest and the lathe center. I think this is the one you mean:

I believe it's the third item down, ref #mw1. Unfortunately for us in the states, Toolmex/Bison doesn't seem to think we need it and it does not appear in their master catalogue here. As I remember it's a piston type of arrangement, but the piston pulls the toolholder in. Makes a bunch more sense. I once ran into a web site calling this toolpost a "Dickson" type. The cat's meow for the Myford and the Emco may perhaps be the small series KDK, but save your pennies, it'll set you back something like $500. Personally, I use a Phase II piston type and mill down the underside of the tool holders a bit so the center height works out. The steel is not very impressive, I guess you'd have to say it's been softened rather than hardened! Chronos says they can export to the states so I'm thinking of giving the Bison a try. I like Bison stuff - made in Poland - a whole lot and own a bunch of it.

Please let us know how you like yours, Charles Morrill

Oh well, the url almost works, search on the Chronos site for lathe toolposts if your still interested...

Just to let you know, these ARE now available here. We can provide the Bison QC Toolpost, but at least for now, these are for lathes slightly larger than the Logan.

Although they are listed as being for as small as 10" dia swing, the smallest set is made to accommodate a 3/4" turning tool, and has a minimum center height of 1.44".

If you would like more information, email me directly.

Sorry for taking a while to reply, but the one on the Chronos site wasn't the one I have. I used it a few more times since my original post and have put a bit more pressure down on the clamp screws thinking " Well, if she snaps it will give me another chance to complain that they dont make things like they used to " !

It must be stronger than it looks.
